    Description / Table of Contents: Summary Background and Objective: Pemphigoid gestationis (PG) is a rare pregnancy-associated autoimmune bullous disease characterized by autoantibodies to the 180 kD bullous pemphigoid antigen (BP180). The clinical spectrum of PG is polymorphic and for diagnostic purposes, a skin biopsy is usually taken demonstrating the deposition of autoantibodies. Patients and Methods: From 2 patients, skin biopsies were obtained for histopathologic and immunofluorescence studies. Circulating autoantibodies were characterized by immunoblotting and ELISA using a recombinant form of the immunodominant BP180 NC16 A domain. Results: The 2 PG patients described here did not show blisters but complained about severe itching. In the first case, PG presented in the first trimester of the second pregnancy as an erythema-multiforme-like disease. The second patient developed urticarial plaques a few days after delivery. PG was diagnosed by the detection of autoantibodies against recombinant BP180 NC16 A by immunoblot and ELISA analysis and confirmed by linear deposits of C3 at the cutaneous basement membrane zone on direct immunofluorecence microscopy. Skin lesions healed with oral prednisolon. Conclusions: In our two patients, non-bullous PG could be diagnosed by serological tests. Immunmoblotting and ELISA might be sensitive and specific tools when screening sera of patients with pruritic skin lesions in pregnancy for the presence of autoantibodies to BP180. In some cases, these newer techniques may make a skin biopsy unnecessary.
    Notes: Zusammenfassung Hintergrund und Fragestellung: Das Pemphigoid gestationis (PG) ist eine seltene, schwangerschaftsspezifische Autoimmundermatose mit Autoantikörpern gegen das 180 kD bullöse Pemphigoid Antigen (BP180). Das klinische Bild ist polymorph. Die Diagnose des PG wird meist anhand einer Biopsie mit Nachweis der Autoantikörper in der Haut der Patientinnen gesichert. Patienten/Methodik: Bei 2 Patientinnen wurden Hautbiopsien histopatholgisch und immunfluoreszenzoptisch untersucht. Die Autoantikörper wurden mittels Immunoblot und ELISA unter Verwendung einer rekombinanten Form der immundominanten BP180-NC16-A-Domäne charakterisiert. Ergebnisse: Bei den beiden vorgestellten Patientinnen verlief das PG ohne Blasenbildung, jedoch mit starkem Juckreiz. Bei unserer ersten Patientin manifestierte sich die Erkrankung im 1. Trimenon unter dem Bild eines Erythema multiforme, der 2. Fall trat wenige Tage postpartal unter dem Bild einer Urtikaria auf. Die Diagnose wurde jeweils durch den Nachweis von Antikörpern gegen rekombinantes BP180 NC16 A im Immunoblot und ELISA und durch lineare C3-Ablagerungen an der Basalmembran in der direkten Immunfluoreszenz gesichert. Die Hautveränderungen heilten bei beiden Patientinnen unter oraler Prednisolontherapie ab. Schlussfolgerung: Bei den beiden vorgestellten Patientinnen wurde anhand von Serumuntersuchungen ein PG ohne Blasenbildung diagnostiziert. Sowohl Immunoblot als auch ELISA erscheinen aufgrund ihrer hohen Sensitivität und Spezifität als Screeningverfahren zum Nachweis von Autoantikörpern gegen BP180 bei pruriginösen Schwangerschaftsdermatosen geeignet. In der Zukunft dürften sie mitunter die bisher unverzichtbare Hautbiopsie zur Diagnose eines PG ersetzen.

    Notes: Bullous delayed pressure urticaria (DPU) is a rare variant of DPU. Treatment of DPU is difficult and the underlying pathogenic mechanism of DPU remains elusive. We report a 72-year-old man with DPU and associated chronic urticaria as well as delayed urticarial dermographism. Pressure challenge gave rise to a deep weal covered by multiple vesicles and bullae after 24 h. Histological examination of a skin biopsy specimen obtained 24 h after pressure challenge demonstrated intraepidermal bullae filled with eosinophils accompanied by a dense, predominantly eosinophilic infiltrate in the dermis. Whereas the numbers and morphology of mast cells were unaltered, the extracellular deposition of eosinophil cationic protein revealed evidence for eosinophil activation. Concomitantly, both CD4+ and CD8+ T lymphocytes were present in the infiltrate and expressed interleukin 5. As bullous DPU may represent the maximal variant of DPU, the investigation of the cellular infiltrate and the chemokines/cytokines released may reveal potential pathogenic mechanisms. A possible effector role of eosinophilic granulocytes, T-cell subsets and mast cells is discussed.
